Configuration settings for MSA2000 systems
The MSA2000 System Storage® Management Utility (SMU) provides configuration settings and options that can be used with Storwize® V3500 clustered systems.
Target port options
Table 1 describes the port settings that are supported by the Storwize V3500.
Option | Values (any limits on the possible values) | Description |
---|---|---|
Host Port Configuration | 2 Gbps or 4 Gbps | Set according to the fabric speed. |
Internal Host Port Interconnect | Straight-through | Set to Straight-through for a point-to-point Fibre Channel connection. |
Host Port Configuration | Point-to-Point | Set to Point-to-point for use with Storwize V3500. |
LU options and settings
The MSA volumes
can be created after you create a volume (RAID
0 is not supported), or they can be added
later to the volume. LUNs can
be configured in 16K, 32K, and 64K (default) chunks by using the advanced
option. Table 2 describes
the preferred options available when you create a logical unit (LU).
Option | Value | Description |
---|---|---|
Expose to All Hosts | Yes | After the mapping of the volume to the Storwize V3500 completes, this is modified to All other hosts (none no access). This can be done under the Assign Host Access Privileges frame. |
Automatically assign LUNs | Yes | This forces option expose to all hosts and is necessary for consistent LUN numbering. |
write-policy | write-back | |
optimization | any | |
read-ahead-size | default | |
independent | disable | This setting controls cache mirroring. Because Storwize V3500 requires mirroring, the independent=disable option must be used. |
Host options and settings for MSA2000 systems
There is no specific host option to present the MSA2000 systems to Storwize V3500 systems. Use a valid Microsoft Windows operating system as the host setting for Storwize V3500.
